Depending on the symptoms you are having, we may want to have Intestinal Panels run in an off site lab. These panels can identify specifically what the terrain is in the Gut, be it Bacterial, Parasites, or just general Ecology of the Large Intestine.
With years of poor diet, overuse of antibiotics and other medications, surgeries, dehydration and excess emotional stressors the terrain of the gut degrades. Fortunately, the body wants to be healthy and if we give it the right tools, it will rebuild.
